Maize plants with severe zinc deficiency in the foreground, with healthier plants (planted at the same time) in the background. Zinc deficiency is common in many different types of soil; some soils (sandy soils, histosols and soils developed from highly weathered parent material) have low total zinc concentrations, and others have low plant-available zinc due to strong zinc sorption ...
The Center for Plant Health Science and Technology (CPHST) is PPQ's scientific support division, providing research and data to make scientifically valid regulatory and policy decisions. The center also develops technology and practical tools for PPQ personnel to conduct pest detection, exclusion and management operations.
Animal and Plant Health Inspection Service (APHIS) and its Plant Protection and Quarantine (PPQ) are responsible for safeguarding agriculture and natural resources from the risks associated with the entry, establishment, or spread of animal and plant pests and noxious weeds. Phytosanitary certification is provided as a service to U.S ...

While the IPPC's primary focus is on plants and plant products moving in international trade, the convention also covers research materials, biological control organisms, germplasm banks, containment facilities, food aid, emergency aid and anything else that can act as a vector for the spread of plant pests – for example, containers, packaging materials, soil, vehicles, vessels and machinery.
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".
